keep in mind that these are not level 100.all critizisms and suggestions will be much aprecciated.i havent ev trained them so they may be weak stat wise.

slaking get rid of slash and slack off and teach it rest and sleep talk.

dragonite get rid of all its moves except outrage and teach it roost, earthquake and thunderpunch.

Lucario's fine except instead of shadow ball teach it extreme speed because it has a low speed.

Tyranitar teach it aerial ace instead of thunderbolt.

Garchomp keep dragon claw, earthquake and teach it shadow claw and aerial ace instead of flamethrower and giga impact.

Charizard keep flamethrower and dragon pulse and teach it roost and er... solerbeam.

That is just a suggestion, someone else will probally think of a better team.
